BEAMLESS BRAKE.

To (LZZ 1071 0722, it may concern Be it known that we, HARVEY L. JONES and Roy ANDERSON, citizens of the United States, residing at Charleston, in the county of Coles, State of Illinois, have invented a new and useful Beamless Brake, of which the following is a specification.

The device forming the subject matter 01' this application is a brake, adapted to be employed upon rail way rolling stock 01' all sorts.

The invention aims to provide a brake in which the transversely extended brake beam may be dispensed with.

Another object of the invention 18 to provide a pair of brake carrying members movable parallel to the wheels and adapted to ei'igage the wheels.

Another object of the invention to provide novel means for actuating the brake carrying members.

It within the scope of the invention to improve generally and to increase the utility of, devices oi. that type to which the present invention appertains.

WVith the foregoing and other objects in view which will appear as the description proceeds the invention resides in the combination and arrangement of parts and. in the details 0:1 construction hereinafter described and claimed, it "being understood that changes in the precise embodiment of invention herein disclosed can be made'within the scope of what claimed without departing from the spirit of the invention.

In the drawing :Figure 1 shows the invention in top plan, the actuating mechanism being shown diagralnmatically; Fig. 2 is a side elevation; Fig. 3 is av perspective showing the brake bars in perspective and separated from each other; and Fig. 4: is a perspective of one of the actuating levers.

In the drawing, the numeral 1 indicates the truck beam, and the numeral 1 indicates the sand board. The beam 1 is provided with an outstanding bracket 2 upon which is fulcrumed intermediate its ends an actuating lever 3. A connecting rod 4i is united with the upper end of the lever 8, the connecting rod 4: being united with one end of the lever 5, the other end of which is fillcrumed as indicated at 6 upon a support 7 which may be upheld in any desired manner. A connecting rod 8 is pivoted as indicated at 9 to the intermediate portion of the Specification of Letters Patent.

lever 53, one end of the rod 8 being pivoted as indicated at 10 to a lever 11 connected as mdicated at 12 to the piston rod 1 1 of a brake cylinder 15. To one end of the lever 11 is pivoted a connecting rod 16, permitting a simultaneous operation of two sets of the brake mechanism to be described hereinafter.

Located adjacent the ends of the sand board 1 are supports 17 in which brake bars 18 and 1.) are mounted to slide, in superposed relation, parallel to the wheel30. A head 46 is pivotally connected with the lower end. oi the actuating lever 3, the head 46 being pivotally connected with the adjacent,

inner ends of a pair of oppositely extended levers 20. The brake bars 18 and 19 are equipped with oppositely extended tongues 21 having openings 22. The lever 20 is fulcrumed, as shown at 23, in one 01 the open lugs 22 in one brake bar and is pivotally mounted. in the diagonally disposed opening 22 in the other brake bar, as indicated at 24:. The openings 22 afford, what, for convenience, may be denominated loose connec tions between the bars and the lever. The bars 18 and 19 are longitudinally slotted as indicated at 25 and pins 26 are mounted in openings 25 in the bars, the pins 26 being adapted to move in the slots 25 to direct the relative sliding movement between the bars 18 and 19. There are several of the openings 25 so as to permit a shifting of the pins 26, thereby to adjust and limit the bars 18 and 19 in their sliding movement. The bars 18 and 19 as shown at 27, are offset at their ends for connection with brake heads 28 carrying shoes 29 adapted to bear upon the peripheries oi the wheels 30. Hangers 4.4 are connected with the brake heads 28, the hangers -.l-.-il-. being pivotally connected with the usual lugs of the truck beam 1.

In operation, motion is imparted to the lever 11 from the piston rod 14, the lever 11 actuating the connecting rod 8, the latter tilting the lever 5 and the lever 5 through the medium of the connecting rod 1, tilting the actuating lever 8. The lever 3, swinging upon its fulcrum 2 will actuate the levers 20, and when the levers are tilted, the brake bars 18 and 19 will be thrust in opposite direc tions, the brake shoes 29 being advanced against the wheels 80. Obviously, a release of the brakes is effected by reversing the operation above described.

The members 17 serve to uphold the bars 18 and 19, should the hangers 4 break loose from the truck.

Having thus described the invention, what is claimed is 1. In a device of the class described, a pair of bars disposed in superposed and overlapped relation the bars being united for right line movement; means for supporting the bars; shoes located adjacent the outer ends of the bars; a lever; and connections between the lever and the bars, one connection constituting a fulcrum for the lever and the other connection being a pin and slot union, permitting a tilting of the lever and a right line movement between the bars.

2. In a device of the class described, a pair of alined superposed bars provided intermediate their ends with outstanding tongues; a lever fulcrumed on one tongue to one side of the bars and pivoted to the other tongue upon the opposite side of the bars, the connection between one tongue and the lever being a loose connection; interengaging elements connecting the bars for right line movement in the direction of their lengths; shoes carried by the remote ends of the bars; and supports located upon opposite sides of the tongues the supports receiving the bars slidably.

In testimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presence of two witnesses.
